Application February 15, 1949, Serial No. 76,603

This invention relates to sawbucks or saw tables, and more particularly to a sawbuck for attachment to a portable, power saw.

It is an object of this invention to provide a sawbuck for attachment to a portable or movable, powered, rotating saw which may be readily attached to and detached from the support for the saw in such a manner that the elongated logs or planks may be cut to desired length at the place where they are found. The sawbuck is so formed and related to the saw that one man can position the log or pole on the sawbuck in a position to be cut. Heretofore long poles or other elongated objects to be out have been transported by suitable conveying means to a sawmill or saw table where the pole was cut into desired lengths. The transportation of the pole and the handling of the pole on the saw table, which is very short relative to the length of many poles, required the work of several men. It is an object of this invention to provide a sawbuck for use in cutting long poles whereby one man may handily raise one end of the pole onto the sawbuck to a position where the pole will be cut to selected lengths and the cut lengths may be then handled by one man for transportation.

Still another object of this invention is to provide a light-weight sawbuck for attachment to a portable, power saw, which may be handled easily by one man in moving, with the portable saw, to selected places where the poles to be cut may be found.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a side elevation of the one-man sawbuck constructed according to an embodiment of my invention, supported on a wheeled, power saw;

Figure 2 is a to plan view of the sawbuck, with the powered saw broken away;

Figure 3 is a perspective view, partly broken away and partly in section, of the sawbuck removed from the circular saw and power means therefor.

Referring to the drawings, the numeral ll] designates generally a portable, powered saw of conventional construction, having a circular saw member or blade ll powered by a motor 12. The circular saw I l and motor l2 are supported on a wheeled frame l4 for movement to a selected or 2 Claims. (Cl. 143-43) desired position. The saw II is rotatably supported in an elongated bearing [5, fixed on the outer ends of a supporting rod l6 fixed on the frame I l.

The saw [I is fixed on a shaft I! which is rotatably engaged in a bearing l5 having a pulley l8 fixed thereon on the opposite side of the bearing l'5 from the saw H. The shaft H, together with the circular saw H is rotated by a flexible member l9 engaging about the pulley l8 and a driving pulley, not shown in the drawings, rotated by the motor l2.

The sawbuck 29, constructed according to an embodiment of my invention, is formed of lengths of angle bars fixed together to form a frame for disposition adjacent the saw I l in a plane parallel to the plane of the saw for supporting one end of an elongated pole or log to be cut by the saw.

The sawbuck 20 is formed with an elongated lower bar member 2|. which is adapted to lie flatly on the surface of the ground. A verticallyextending end member 22 is fixed on one end of the lower member 2| extending upwardly therefrom. An upwardly and forwardly-inclined end member 24 is fixed on the other end of the lower, horizontal bar 2|, and an upper bar 25 is fixed on the upper end of the upwardly-extending supporting bars 22 and 24. The upper and lower bars 2| and 22 are formed of right-angled bars having horizontal flat lower and upper flanges and inwardly-extending flanges. The end members 22 and 24 are also formed of right-angled bars having fiat outer flanges and inwardly-extending flanges disposed substantially in alignment with the inwardly-extending flanges of the upper and lower members 25 and 2|, respectively.

The upper member 25 is inclined downwardly and inwardly toward one end, the inner end, when the sawbuck 20 is secured on the bearing l5, so that the log, or other material to be cut may more readilybe moved along the length of the upper member 25 toward the cutting edge of the saw ll.

At the lower end of the upper member 25, the downwardly and inwardly-extending flange 2B is cut away and the upper horizontal flange 21 thereof is depressed or bent downwardly to form a concave, semi-cylindrical bearing seat 28. The bearing seat 28 is disposed adjacent the upper end of the end supporting member 24, whereby the supporting member 24 may be considered as substantially engaged with the seat 28 as a vertical support therefor. An intermediate tubular supporting member 29 extends downwardly and outwardly from the lower surface of the seat 28 for engagement with the lower supporting bar 2| intermediate the length thereof. The supporting members 24 and 29 provide direct supports for the seat 28 in which the bearing I for the circular saw H is adapted to be engaged.

A second intermediate supporting member 30 is fixed-betweentheupper andlowerbars 25 and 2| intermediate the length thereof outwardly from the supporting member 29 and is particularly arranged for supporting the work to be engaged on the upper surface of the work-supporting member 25.

The intermediate supporting member30 istubular in formation, similar to the supporting member 29.

A bracket 3|, semi-circularin configuration, is adapted to be secured on the upper member 25, over the seat 28 for securing the bearing l 5'on the member 25. The member 3| is semi-cylindrical, having the same 'diameteras the semicylindrical sleeve 28, and is adapted to be mounted on the-bar 1253 confronting the sleeve 28 to. provide a clamp for securing the bearing l5 onto the sawbucklii.

member 3| is formed with-a pair of-outwardlyextending, oppositely-directed arms 32 which flatly overlie the horizontal flange 27 of the member 25, and bolts 34,-orother suitable fastening "devices, are engagedthrough the-arms 34 for se- "curin'gthe clampingmember 3| over the sleeve .28.

A* guide member or stop lug 35 is formed on the upper end of the longitudinally-extending upber member '25 for limiting the outward movement of the'log 'or work outwardly on the sawbuck 20. The stop 35 is formed as a continuation of the horizontal'fiange 27 of the angled lipper member 25.

A downwardly and-inwardly-inclined anchor 'member 36 is fixed to or'formed integrally with the'inner verticalmember 24 or the lower horizontal' member 2 l, extending downwardly and inwardly from the corner formed-by the'intersection "of'the members 2| and 24. member 3t may be'formed as'a continuation of the horizontal 'flangeof either ofthemem'bers -2| or 24, and the anchor member '36 extends downwardly and'inwardly in the direction of the power member Hi.

-In the use -and operation of the 'sawbuck 20, .th'e'portable saw member i6 is moved to adesirable location. The clamping member 3| is removed from theupper member 25st) that the bearing l5 of the saw may be engaged in-the seat'28. The member 3| is then'secure'd to the fiange 2! of the upper member 25 "for-clamping the sawbuck '20 onto the bearing 1'5. A log or 'othenob'jectto be cut may thenbe'positioned [so that one end is resting on the'horizontalmember 25'near the outer upper end thereof. "While one man could not lift anentire log up onto'a saw table to be out by the circular saw, one man could lift one end of a log to rest on the upper side of the upper member25'of the sawbuck 20. The log is'then moved downwardly and inwardly on the sawbuck 20 for-engagement with the rotating circular saw H; where the log may be cut into any desirable lengths. The other-endof 'the "'log maybe rested on the ground orflif desired,
